- Typical Performance and Required Loadings
- ZinClear-IM can be formulated at high loadings to achieve high SPF without compromising the clarity of the end product.
- The table below serves as a guide only, as the SPF will additionally depend on the type of formulation.
SPF Target ZinClear-IM Loading Equivalent ZnO Loading
<15 15-25% ~7.5-12.5% 15-25 30-40% ~15-20% 30+ 40-50% ~20-25% Antaria recommends that formulators conduct in vivo SPF testing when possible during product development to ensure reliability of results.
- Particle Morphology
The zinc oxide particles in ZinClear-IM consist of primary particles, which form aggregates up to a few tens of micrometres in size. Larger aggregates have a unique porous structure that provides a closer match between the refractive index of the particle and the refractive index of the emollient, resulting in high transparency. A typical SEM image of the zinc oxide particles in ZinClear-IM is shown in the image below. This image illustrates that the zinc oxide is present in the form of porous particles having sizes mostly in the micrometer range.
